This was split into two days. One day for prisms and one day for cylinders.
We looked at prims, in two parts. First a box shape, that students were familiar with. Then we looked at skewing as cutting into a bunch of layers, infinitely many in fact. This helped students to understand why the volume doesn't change.
On the second day we did the same for cylinders. Extra time was used to go over questions from homework, and give the students a chance to get their work done in class.
